I'm trying to add some fields to a shapefile using pyshp. The code I have to far is:
import shapefile # Read in our existing shapefile r = shapefile.Reader(r"C:\...\Edit_SHP\TracksLines.shp") # Create a new shapefile w = shapefile.Writer(r"C:\...\Edit_SHP\TracksLines_edited.shp") # Copy over the existing fields w.fields = list(r.fields) # Copy over the records for shaperec in r.iterShapeRecords(): w.record(*shaperec.record) w.shape(shaperec.shape) w.field('test')
The issue is that when I try to add a new field all the records already present on the shape are messed up.
How can I keep the same numbers of records, when adding new fields?
